Half-baked knightship is a class of knightships based on the well-known half-bakery reaction with a glider. Representatives of this class are currently the smallest known oblique spaceships in terms of the bounding box, while Gemini has fewer cells.
Components and slow salvo syntheses for the ship were found by the combined efforts of Chris Cain, Ivan Fomichev and Dave Greene. Adam P. Goucher proposed the base design for the ship [1] and wrote a Golly script that can put the components together into a working knightship [2] of any sufficiently large period (above about 2.3 million generations).
In May 2014 Ivan Fomichev found the key reactions, which allow long chains of half-bakeries to regenerate themselves at (6,3), and also to regenerate seed constellations at one end of the ship. When triggered, the seeds produce the small glider salvos that mediate the (6,3) offset reaction.
Like the (2,1) self-reconstructor, this knightship moves very slowly, but unlike a self-reconstructor, only a tiny fraction of the half-baked knightship has an embedded construction recipe. The half-bakery chains encode a small slow salvo recipe, but the positions of the half-bakeries are not encoded anywhere else.
